About Ballism. General Information. Hemiballism involves involuntary, violent movements on one side of the body. They are especially violent because they involve the muscles where the limbs attach to the body. The most common cause is stroke or tumor. Symptoms

Hemiballismus or hemiballism is a basal ganglia syndrome resulting from damage to the subthalamic nucleus in the basal ganglia. [1] . It is a rare hyperkinetic movement disorder, [2] that is characterized by pronounced involuntary limb movements [1][3] on one side of the body [4] and can cause significant disability. [5] .

Definition: Ballism is a rare movement disorder causing involuntary, flinging movements. Causes: It often results from brain damage due to stroke or traumatic injuries. Symptoms: Patients experience rapid, erratic motions primarily affecting one side.

Hemiballismus is unilateral rapid, nonrhythmic, nonsuppressible, wildly flinging movement of the proximal arm and/or leg; rarely, such movement occurs bilaterally (ballismus). Hemiballismus may be considered a severe form of chorea. (See also Overview of …

Jul 19, 2019 · Hemiballismus, (previously known as ballism) is an extremely rare movement disorder which occurs as a result of decreased activity of the subthalamic nucleus in the basal ganglia, which causes ballistic, flailing and unwanted movements of the limbs. 1 Certain metabolic abnormalities can also cause this condition, although this is rare ...

Ballism is a rare disorder characterized by flailing proximal limb movements and by its traditional association with pathology at the subthalamic nucleus of Luys (STN). In recent years, the STN has become a focal point in models of basal ganglia pathophysiology.
